Then, a question : I'm trying to make a little game to gain some skill with both CS and CEL, and the goal is to have the player represented by a 2D sprite, but within a 3D world. Kind of like Xenogears (on Playstation) or Ragnarök online. But, trying to use a Sprite2D as the player entity didn't work (I'm currently using b2cs to try things out).

So, is there something special to do in order to have a nice little 2D sprite running and jumping around ? Or does it involve writing special behaviours and/or property classes ?
